• 802.1X authentication using pre-shared keys or an EAP type, required for WPA2
and WPA.
• Data encryption and decryption using WPA2 AES, WPA TKIP or WEP.
Common EAP types include:
•
EAP-TLS: Uses the same technology as a follow-on to Secure Socket Layer (SSL). It
provides strong security, but relies on client certificates for user authentication.
• PEAP: Provides secure user authentication by using a TLS tunnel to encrypt EAP traf-
fic. Two different inner methods are used with PEAP:
- EAP-MSCHAPV2, resulting in PEAP-MSCHAP: This is appropriate for use against
Windows Active Directory and domains.
- EAP-GTC, resulting in PEAP-GTC: This is for authentication with one-time pass-
words (OTPs) against OTP databases such as SecureID.
• LEAP: Is an authentication method for use with Cisco WLAN access points. LEAP
does not require the use of server or client certificates. LEAP supports Windows Active
Directory and domains but requires the use of strong passwords to avoid vulnerability to
offline dictionary attacks.
• EAP-FAST: Is a successor to LEAP and does not require strong passwords to protect
against offline dictionary attacks. Like LEAP, EAP-FAST does not require the use of
server or client certificates and supports Windows Active Directory and domains.
SCU EAP Types
The following EAP types are supported by the integrated supplicant and can be configured
in SCU: PEAP-MSCHAP, PEAP-GTC, LEAP and EAP-FAST. With each of these four
types, if authentication credentials are not stored in the config, you will be prompted to enter
credentials the first time the radio attempts to associate to an access point that supports
802.1X (EAP).
Consider the following when configuring one of the EAP types:
•
PEAP-GTC: SCU supports static (login) passwords only.
• LEAP: Strong passwords are recommended.
• EAP-FAST: SCU supports automatic, not manual, PAC provisioning.
EAP-TLS will work with a Summit DC-802.11 SC CF (Model RA2041) radio module
when Windows Zero Config (WZC) rather than the SCU is used to configure the type. With
WZC, the native Windows supplicant instead of the SCU integrated supplicant is used.
Note: PEAP and EAP-TLS require the use of Windows facilities for the configura-
tion of digital certificates.
